Question

I have a text string like this:

<dt>
  <span>
    <tag:text name="fee" />
  </span>
</dt>
...
<tag:text name="amount" />    

what I want is to find all tags of type

<tag:text 

and then collect a List with the values from the name element:

"fee"
"amount"

Answer 1

(?<=tag:text name=").*(?=") 

test with grep:

kent$  echo '<dt>
      <span>
        <tag:text name="fee" />
      </span>
    </dt>
    ...
    <tag:text name="amount" />   '|grep -Po '(?<=tag:text name=").*(?=")' 

    fee
    amount
